CSV Outputformat - Allow list of values to be returned as a comma separated string
Description
Currently, For the WFS CSV output format, any nested attribute with multiple cardinalities is ignored. we need to extend the encoder to detect if the nested attribute is a list of simple values (strings, numbers, dates, etc ...) and if that's the case encode it as a comma-separated list of values.
